i This invention relatestotools or accessories intended for use bytelephone and telegraph provision of novel climbing irons by meanslinemen, and has for its object the 1 of which a linemanmay readilyclimb poles for the purpose of making repairs,

ments or the like.

An important object is the provision of climbing irons which are simpleand inexpensive to manufacture, easy which to adjust, and

are, moreover, of such construction that the parts thereof may be veryreadily disassembled for convenience in transportation or storage.

Anotherob ect s to provide climbing irons which, most p when in appliedposition, will be ositive in their holding action so that there will beno probability or possibility or the user slipping and falling.

Another obj'ectis to provide a structure or device of this characterwhich will be simple and inexpensivem manufacture, positive in action,efficient and durable in service, and a general W1th the above andimprovement in the art.

other objects and adantages in view, the invention consists in the novelconstruction elements to be hereinafter morev fully described andclaimed, and illustrated 1D. the

accompanying drawings,

Figure 5 is a perspective view of one-of the foot or shoe engagingmembers, and

Figure 6 is on the a detail in cross section taken line 66 of Figure 1.

Referring more particularly to the drawings,

- iron I have shown each of the climbing devices for each footascomprising a substantially quarter circular bar member 10 formed ofiron,

steel'or other suitable material and provided with a plurality of spurstratingly engaged shaped and arrangedas to be penewithin a pole or thelike to be climbed by the user. Associated and ted with each of thesemembers is a foot piece 12 which may be convenientlyv formed as acasting or stamping and which includes the plate portion 13provided atits ends with purpose to be.

bers 1 flanges l4 slotted at 15 fora described. a Each of the mem- 2further includes a guide element ad] ustand arrangement of 5 a is aperspective view of the at-.

gated strap member 22' engaged through one slot 15, and riveted to ahorizontally arranged strap member 23 which 1s, in turn,

carries an adjusting buckle 25 by means of which connection may bemadeabout the 1 foot of the user regardless of the size of the foot or theshoe.

In the operation of the device, it will be seen that when the userwishes to apply one of the devices to his foot, the foot piece isengaged with the slidably engaging the housing member 16 thereon, andwhen the proper position is ob-, tained the spring pressed pin orplunger 18 will engage within the recess or socket 20, thereby holdingthe foot piece firmly with respect to the arcuate bar. The operator Thestrap member 2a arcuate member 10 by then places his foot upon themember 12 and secures the strap 22 over hisinstep by means of the buckle.25. clear that one of the devices is placed on each foot. Afterthedevices are placed in position in this manner and secured as indi:cated, it is obvious that the lineman or other person thus equipped mayeasily climb a pole in the well known'manner, the prongs or spurs 11biting into the pole and providing an adequate grip thereon so as toprevent any possibility-of slipping or fall ing. W hen use of the deviceis not desired,

it is clear that the pin 18 may be retracted by pulling foot piecemember 10 stored within a tool box or other receptacle. It is believedthat the construction, operation and advantages will be readily apparentto one skilled in the art without further explanation,

upon the head thereof and the It is of course disassembled with respectwas so thatthe parts may be easily While I have shown and 'described thev preferred embodiment of the invention, it

should be understood thatI reservethe right to make suchchanges in the'forin, constructionand arrangement of parts as will not depart from thespirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I claim In a climbing iron of thecharacter described, an arcuate bar provided at its concared side withpenetrating prongs, and at taehing means for said bar comprising a footpiece of plate-like form provided at one end with an upstanding ear andprorided in spaced relation to its other end with a similar upstandingear, said ears being provided with elongated slots, a fool: engagingstrap structure engaged with the slotted ears, one end of said platemember being prolonged beyond the second named ear and formed to providea housing slidably receiving one end of said arcuate bar, said end ofthe bar being formed with :1 recess and with an inclined notch leadingfrom the end toward said recess, an enlarged guide portion on saidhousing, a spring located within said enlarged guide portion, and a pinslidabl mounted within said enarged guide portion and normally urged bysaid spring doii'nwardly for engagement within the recess in said bar,the notch in Ffiltl bar acting io ell'ect retraction oi the pin when thebar is inserted within the housing.

In liefitiniolrx whereof I allix ture.
